I haven't tried it, but I don't see a reason why the Linux binary
of Netscape should not work. The only thing you might have to do
is add a config file to /emul/linux/etc to keep the Linux resolve
library code happy.

That, and taking care of the system calls. See /sys/compat/*/* for
how this is done for the various compat modes. And grep for COMPAT_
through all the rest of the kernel code if you want to be thorough..
